Description

Die Erfindung betrifft eine Federlatte für eine Unterpolsterung für Sitz- oder Liegemöbel, deren Polsterfläche mit aufgesetzten Federelementen in Teilflächen aufgelöst und mit einer Polsterauflage versehen ist, wobei die Federlatte zumindest einen nach unten geöffneten Leistenkörper aufweist, der beidseits mit Endstücken versehen ist zum Festlegen an dem Sitz- oder Liegemöbel, insbesondere an einem Lattenrost eines Bettes.The invention relates to a spring bar for a padding for sitting or lying furniture, the cushion surface is dissolved with patch spring elements in sub-areas and provided with a cushion pad, wherein the spring bar has at least one downwardly open strip body, which is provided on both sides with end pieces for fixing to the Seating or reclining furniture, in particular on a slatted base of a bed.

Sitz- oder Liegemöbel, insbesondere Betten weisen Polsterflächen auf, die von Polsterauflagen (Matratzen o.dgl.) gebildet sind, die ihrerseits auf einer Unterpolsterungen aufgelegt sind. Als Unterpolsterungen dienen regelmäßig Lattenroste. Um eine physiologische Lagerung des ruhenden Körpers zu erreichen, soll das Bettsystem mit der Unterpolsterung eine hinreichende Absenkung im Schulter- und im Beckenbereich zulassen, so dass die Wirbelsäule in Rückenlage und auch in Seitenlage im wesentlichen gestreckt liegt. Dazu sind in den Gestellen von Sitz- oder Liegemöbel, insbesondere in den als Gestell anzusehenden Lattenrosten von Betten zwischen deren Längsholmen querliegend angeordnete Latten vorgesehen, die die Polsterauflage aufnehmen, und die als Federlatten ausgebildet sind. Die Lattenköpfe sind beidseitig mit Endstücken versehen, die das Festlegen an dem Gestell bzw. an den Längsholmen erlauben, die - zur Verbesserung des Liegekomforts - auch unterteilt und mit Gelenken aneinander gelenkt sein können, um das Kopfteil oder das Fußteil aufstellen zu können.Sitting or lying furniture, especially beds have upholstered surfaces, which are formed by cushions (mattresses or the like.) Which in turn are placed on a padding. As Unterpolsterungen serve regularly slatted frames. In order to achieve a physiological storage of the dormant body, the bed system with the padding a sufficient reduction in the shoulder and in the Allow pelvic area, so that the spine is substantially stretched in a supine position and also in a lateral position. For this purpose, in the racks of sitting or lying furniture, in particular to be regarded as a frame slats of beds between the longitudinal beams transversely arranged slats are provided which receive the cushion support, and which are designed as spring slats. The lath heads are provided on both sides with end pieces, which allow the fixing to the frame or on the longitudinal beams, which - can also be subdivided and articulated to each other to improve the Liegekomforts - to set up the headboard or the footboard.

Zur weiteren Verbesserung des Liegekomforts ist aus EP 0 401 712 und EP 0 653 174 bekannt, die Sitz- oder Liegefläche nicht nur durch Federlatten in Längsrichtung zu unterteilen, sondern auch durch Federelemente in Querrichtung, so dass eine in Einzelflächen aufgelöste Liegefläche entsteht. Bei derartigen Polstersystemen ist wegen der speziellen Ausbildung der Federung der Einsatz (relativ) dünner und somit auch leichter Polsterauflagen ohne Komfortverlust möglich. Dazu werden nach EP 0 401 712 Starrlatten eingesetzt, die als U-Profile mit hochstehenden Flanschen die Federelemente aufnehmen und deren Hub begrenzen.To further improve lying comfort, it is known from EP 0 401 712 and EP 0 653 174 to subdivide the sitting or lying surface not only by spring slats in the longitudinal direction, but also by spring elements in the transverse direction, so that a lying surface which is dissolved in individual surfaces is created. In such padding systems is due to the special design of the suspension of the use (relatively) thinner and thus also easier cushion pads without loss of comfort possible. For this purpose, according to EP 0 401 712 rigid slats are used, which receive as U-profiles with upstanding flanges, the spring elements and limit their stroke.

Aus dem deutschen Gebrauchsmuster 297 21 656.2 ist zur Bildung einer Polsterfläche eine Federlatte bekannt geworden, von der eine Anzahl parallel zueinander verlaufend in dem Gestell eines Sitz- oder Liegemöbels, insbesondere zwischen den zwei Längsholmen eines Lattenrahmens eines Bettes über die Länge verteilt, angeordnet sind. Auf diesen Federlatten sind eine Anzahl von Federelementen in Spalten und Reihen angeordnet, so dass ein im wesentlichen regelmäßiges Muster gebildet ist. Diese Federlatte ist eine Kunststoffleiste von im wesentlichen U-förmigen Querschnitt, deren Lattenköpfe als Endstücke ausgebildet, das Festlegen an dem Gestell des Sitz- bzw. Liegemöbels bzw. an den Längsholmen eines Lattentrostes für Betten erlauben.From German Utility Model 297 21 656.2 a spring bar is known to form a cushion surface, of which a number of mutually parallel in the frame of a sitting or lying furniture, in particular distributed between the two longitudinal beams of a slatted frame of a bed over the length are arranged. On these spring slats a number of spring elements are arranged in columns and rows, so that a substantially regular pattern is formed. This spring bar is a plastic strip of a substantially U-shaped cross-section, the lath heads designed as tails, allow the fixing to the frame of the seat or lying furniture or on the longitudinal beams of a slatted base for beds.

Nachteilig ist hier, dass die Herstellung derartiger Federlatten kostenintensiv und die Montage solcher Lattenroste äußerst arbeitsintensiv ist, so dass eine wirtschaftliche Fertigung nicht ohne weiteres erreicht werden kann.The disadvantage here is that the production of such spring battens costly and the installation of such slatted frames extremely labor-intensive is, so that an economical production can not be achieved easily.

Darauf folgt die dieser Erfindung zugrunde liegende Aufgabenstellung, die bekannten Federlatten derart weiter zu bilden, dass Herstellung und Montage vereinfacht und so wirtschaftlicher werden.This is followed by the object underlying this invention to further develop the known spring battens so that manufacture and assembly are simplified and thus more economical.

Die Aufgabenlösung ist durch die kennzeichnenden Merkmale des Hauptanspruchs gegeben; vorteilhafte Weiterbildungen und bevorzugte Ausführungsformen beschreiben die Unteransprüche.The task solution is given by the characterizing features of the main claim; advantageous developments and preferred embodiments describe the dependent claims.

Bei den Federlatten nach der Erfindung ist der Lattenkörper gebildet von zumindest zwei im Abstand voneinander angeordneten U-Profilen, die nach unten geöffnet sind. Diese U-Profile sind längs ihrer Längserstreckung durch im Abstand voneinander angeordneten Stege sowie an ihren Lattenköpfen durch Endstücke verbunden, die derart ausgebildet sind, dass eine direkte Befestigung an dem Gestell bzw. an den Längsholmen möglich ist. Diese Federleisten, die ihrerseits im Abstand voneinander angeordnet werden, bilden die Basis einer Polsterfläche, auf die Federelemente aufgesetzt werden, wobei eine von den Federelementen getragene Polsterschicht die Polsterfläche ergänzt. Dabei geben die Auflage- bzw. Kopfplatten solcher Federelemente die Geometrie der Anordnung der Befestigungsmittel und somit auch der Federlatten vor. Dadurch können die Federlatten in gewünschten Abständen und parallel zueinander so angeordnet werden, dass die Federelemente ein im wesentliches regelmäßiges Muster bilden, das die Polsterlage als Auflagepolster aufnimmt.In the spring slats according to the invention, the slat body is formed by at least two spaced-apart U-profiles, which are open at the bottom. These U-profiles are connected along their longitudinal extent by spaced-apart webs and at their lath heads by end pieces, which are designed such that a direct attachment to the frame or to the longitudinal beams is possible. This spring strips, which in turn are arranged at a distance from each other, form the basis of a cushion surface, are placed on the spring elements, wherein a cushion layer supported by the spring elements complements the pad surface. In this case, the support or head plates of such spring elements specify the geometry of the arrangement of the fastening means and thus also of the spring slats. Thereby, the spring slats can be arranged at desired intervals and parallel to each other so that the spring elements form a substantially regular pattern, which receives the cushion layer as a support pad.

Um die Federlatten zu versteifen, ist es vorteilhaft, wenn die Höhe des U-Profils in dessen Mitte gegenüber den beiden an dem Längsholm festliegenden Lattenenden größer ist. Diese Mitten-Überhöhung liegt dabei zwischen 1/3-tel bis 2/3-tel der Höhe des U-Profils am Rand. Weiter wird an den freien Enden der Schenkel des U eine Wulst vorgesehen, die nach außen etwa um eine Dicke des Materials des Schenkels übersteht.To stiffen the spring slats, it is advantageous if the height of the U-profile is greater in the center opposite to the two fixed to the longitudinal spar bar ends. This center elevation is between 1/3 to 2/3 of the height of the U-profile at the edge. Next, a bead is provided at the free ends of the legs of the U, which projects outwardly approximately to a thickness of the material of the leg.

Vorteilhaft sind die U-Profile paarweise durch die Stege miteinander verbunden, die in Bezug auf die Längsersteckung der Federlatte quer dazu ausgerichtet sind. Die Stege sind mit Befestigungsmitteln für Federelemente versehen. Vorteilhaft bilden diese Stege mit einer Stegplatte und mit Querwänden eine quer zur Längserstreckung des Lattenkörpers der Federlatte ausgerichtete U-Form. Auf diese Befestigungsmittel werden die Federelemente aufgesetzt. Um die Bauhöhe niedrig halten zu können, sind nach einer vorteilhaften Weiterbildung Stegplatten der Stege napfartig vertieft ausgebildet. Der Fuß der Federelemente kann somit in der napfartigen Vertiefung versenkt untergebracht werden.Advantageously, the U-profiles are connected in pairs by the webs, which in relation to the longitudinal extent of the spring bar transversely are aligned. The webs are provided with fastening means for spring elements. Advantageously, these webs form with a web plate and with transverse walls a transversely to the longitudinal extension of the slat body of the spring bar aligned U-shape. On these fasteners, the spring elements are placed. In order to keep the height low, web plates of the webs are recessed cup-shaped according to an advantageous development. The foot of the spring elements can thus be accommodated sunk in the cup-like depression.

Als Befestigungsmittel für die Federelemente ist bei einer Ausführungsform ein Loch vorgesehen, in das ein an den Fuß jedes der Federelemente angeformter Zapfen eingreift, wodurch das Federelement an der Federlatte festgelegt ist. Bei einer anderen Ausführungsform ist (in aus DE 299 16 753.4 bekannter Weise) als Befestigungsmittel eine T-förmige Anformung vorgesehen, die mit einer langlochähnlich ausgebildeten Öffnung zusammenwirkt und so ein Festlegen des Federelements an der Federlatte ermöglicht. Dabei ist es ohne Bedeutung, ob die Stegplatte oder der Federelement-Fuß mit der T-förmigen Anformung versehen ist und der Federelement-Fuß oder die Stegplatte die langlochähnlich ausgebildete Öffnung aufweisen oder umgekehrt. Zur Vereinfachung der Montage kann die T-förmige Anformung als auf die Stegplatte aufsetzbarer Aufsatz ausgebildet sein.As a fastening means for the spring elements, a hole is provided in one embodiment, in which engages an integrally formed on the foot of each of the spring elements pin, whereby the spring element is fixed to the spring bar. In another embodiment (in DE 299 16 753.4 known manner) as a fastening means a T-shaped Anformung provided, which cooperates with a slot-like opening and thus enables a setting of the spring element on the spring bar. It is irrelevant whether the web plate or the spring element foot is provided with the T-shaped Anformung and the spring element foot or the web plate have the slot-like opening formed or vice versa. To simplify the assembly, the T-shaped Anformung can be designed as attachable to the web plate essay.

Zum Festlegen der Federlatte an dem Gestell des Sitz- oder Liegemöbels bzw. an dem Lattenrost sind die die beiden U-Profile verbindenden Endstücke vorteilhaft plattenförmig ausgebildet und liegen am Gestell bzw. an den Längsholmen des Lattenrost-Rahmens an. So können diese Endplatten in einfacher Weise befestigt werden, ohne dass es etwa einer Vorbohrung für Dübel bedarf. Das Befestigen erfolgt zweckmäßig mit Stiften, Schrauben, ggf. durch Anschießen, was jedoch auch eine Dübelbefestigung nicht ausschließt. Vorteilhaft werden die Endstücke so ausgebildet, dass eine rechtwinklig abstehende Lasche angesetzt oder angeformt ist, mit der die Federlatte an dem Gestell des Sitz- oder Liegemöbels bzw. den Längsholmen des Lattenrostes abstützbar ist. So können die auf die Befestigungsmittel wirkenden Scherkräfte abgefangen oder - wenn die angesetzte oder angeformte Lasche das Gestell bzw. den Längsholm übergreift bzw. in den Längsholm eingreift - sogar aufgehoben werden und in das Gestell des Sitz- oder Liegemöbels bzw. in den Rahmen des Lattenrostes eingeleitet werden.To set the spring bar on the frame of the sitting or lying furniture or on the slatted base, the two U-profiles connecting end pieces are advantageously plate-shaped and are on the frame or on the longitudinal members of the slatted frame. Thus, these end plates can be fastened in a simple manner, without the need for about a pre-drilling for dowels. The attachment is expediently done with pins, screws, possibly by shooting, but this does not exclude a dowel attachment. Advantageously, the end pieces are formed so that a right-angled protruding tab is attached or molded, with which the spring bar on the frame of the sitting or lying furniture or the longitudinal beams of the slatted base is supported. Thus, the shearing forces acting on the fastening means can be intercepted or - if the attached or molded tab engages over the frame or the longitudinal spar or engages in the longitudinal spar - even be lifted and introduced into the frame of the sitting or lying furniture or in the frame of the slatted frame.

Die Federlatten sind zumindest mit dem aus U-Profilen mit den Stegen und mit den Endstücken gebildeten Lattenkörper vorteilhaft in an sich bekannter Weise als einstückiges Spritzguss-Kunststoffteil ausgebildet. Diese Ausbildung erlaubt eine wirtschaftliche Herstellung besonders in größerer Stückzahl. Als Kunststoff wird dafür ein thermoplastisches Material eingesetzt.The spring slats are advantageously formed in a manner known per se at least with the slat body formed from U-profiles with the webs and with the end pieces as a one-piece injection-molded plastic part. This training allows economical production, especially in larger quantities. As a plastic for a thermoplastic material is used.

Zur Erhöhung der Festigkeit und des Durchbiegevermögens wird der Kunststoff vorteilhaft mit einer Faserverstärkung versehen. Dazu sind in einer vorteilhaften Weiterbildung insbesondere langfasrige Pflanzenfasern vorgesehen. Zur Anpassung der Sichtoberfläche können dem Kunststoff auch Füllstoffe in Form von Farbpigmenten zugesetzt werden. Dadurch wird eine farbige Federlatte erhalten, deren Farbe auch zur Kennzeichnung von Federeigenschaften und Durchbiegevermögen benutzt werden kann. In ähnlicher Weise kann dem Kunststoff auch ein natürliches Füllmittel zugegeben werden, vorzugsweise Späne oder Mehl von Holz. Mit diesem Zusatz können holzähnlich aussehende Federlatten gestaltet werden.To increase the strength and the deflection capacity of the plastic is advantageously provided with a fiber reinforcement. For this purpose, especially long-fiber plant fibers are provided in an advantageous development. To adapt the visible surface, fillers in the form of colored pigments can also be added to the plastic. As a result, a colored spring bar is obtained, the color of which can also be used to characterize spring properties and deflection capacity. Similarly, the plastic may also be added a natural filler, preferably wood chips or flour. With this addition, wood-like-looking spring battens can be designed.

Das Wesen der Erfindung wird an Hand der im Folgenden beispielhaft beschriebenen Figuren 1 und 5 näher erläutert; dabei zeigen:

  • Figur 01: Federlatte in Aufsicht (Persp. Schema);
  • Figur 02: Federlatte in Untersicht (Persp. Schema);
  • Figur 03: Federlatte, Längsschnitt (Schnitt I-I, Fig. 1);
  • Figur 04: Einzelheit Längsschnitt;
  • Figur 05: Federlatte, Querschnitt (Schnitt II-II, Fig. 3)
The essence of the invention will be explained in more detail with reference to Figures 1 and 5 described below by way of example; show:
  • Figure 01: Spring bar in supervision (Persp. Scheme);
  • Figure 02: Spring bar in bottom view (Persp. Scheme);
  • FIG. 03: Spring bar, longitudinal section (section II, FIG. 1);
  • Figure 04: detail longitudinal section;
  • FIG. 05: Spring bar, cross section (section II-II, FIG. 3)

Die Figuren zeigen die Federlatte mit dem Lattenkörper 1. Dieser wird von den U-Profilen 3 und 4 gebildet. Diese U-Profile 3 und 4 verlaufen parallel zueinander, sie sind nach unten geöffnet. Zur Erhöhung der Stabilität ist der Federkörper 1 symmetrisch zur Mitte hin nach oben durchgebogen. Dadurch ist die Höhe "H" der U-Profile in der Mitte etwa 4/3-tel bis 5/3-tel der Höhe "h" der U-Profile am Rand (Fig. 3). Vorteilhaft sind an die unteren Außenkanten beider U-Profile Verstärkungswülste 3.1 bzw. 4.1 angeformt. Diese Verstärkungswülste 3.1 bzw. 4.1 stehen etwa rechtwinklig zu den Schenkeln der U-Profile 3 bzw. 4 ab, wobei ihre Tiefe mindestens gleich der Materialstärke der Schenkel der U-Profile 3 bzw. 4 ist. Beide U-Profile sind über Zwischenstege 5 miteinander verbunden, die über die Länge der U-Profile in regelmäßigen Abständen voneinander verteilt sind. Diese Zwischenstege 5 sind dabei mit den zwischen den U-Profilen 3 und 4 verlaufenden Stegplatten 6 und den Querwänden 7 als querliegende U-Formen ausgebildet.The figures show the spring bar with the slat body 1. This is formed by the U-profiles 3 and 4. These U-profiles 3 and 4 are parallel to each other, they are open at the bottom. To increase the stability of the spring body 1 is bent symmetrically to the middle upwards. Thus, the height "H" of the U-profiles in the middle is about 4 / 3rd to 5 / 3rd of the height "h" of the U-profiles at the edge (Fig. 3). Advantageous are the lower outer edges of both U-profiles Reinforcement beads 3.1 and 4.1 formed. These reinforcing beads 3.1 and 4.1 are approximately at right angles to the legs of the U-profiles 3 and 4, wherein their depth is at least equal to the material thickness of the legs of the U-profiles 3 and 4 respectively. Both U-profiles are interconnected via intermediate webs 5, which are distributed over the length of the U-profiles at regular intervals from each other. These intermediate webs 5 are formed with the running between the U-profiles 3 and 4 web plates 6 and the transverse walls 7 as transverse U-shapes.

Jeder der Stegplatten 6 der Stege 5 zwischen den U-Profilen 3 und 4 weist als Befestigungsmittel für Federelemente eine Anformung 8 auf, mit einer Abschlussplatte 9, die derart ausgebildet ist, dass diese Anformung 8 eine etwa T-förmige Form annimmt. Diese Abschlussplatte 9 der T-förmigen Anformung 8 kann durch eine langloch-ähnliche Öffnung in dem Fuß eines (nicht dargestellten) Federelements geführt werden. Das Federelement wird durch Drehung um 90° festgelegt. Vorteilhaft ist es, wenn im Bereich der Anformung eine in Drehrichtung ansteigende Rampe vorgesehen ist, die in 90°-Stellung abbricht. Dadurch ergibt sich eine Verrastung des festgelegten Federelements. Diese Stege 5 werden vorteilhaft zur Aufnahmen des Fußes des Federelementes und der dazu gehörenden Befestigungsmittel napfartig vertieft ausgebildet.Each of the web plates 6 of the webs 5 between the U-profiles 3 and 4 has as attachment means for spring elements on Anformung 8, with a cover plate 9 which is formed such that this Anformung 8 assumes an approximately T-shaped form. This end plate 9 of the T-shaped Anformung 8 can be performed by a slot-like opening in the foot of a spring element (not shown). The spring element is fixed by turning by 90 °. It is advantageous if, in the area of the molding, a ramp ascending in the direction of rotation is provided, which breaks off in the 90 ° position. This results in a locking of the fixed spring element. These webs 5 are advantageously formed cupped for receiving the foot of the spring element and the associated fastening means.

Die beiden äußeren Enden des Lattenkörpers 1 bilden den jeweiligen Lattenkopf 2. An dem Lattenkopf 2 sind die beiden äußeren Enden der U-Profile 3 und 4 zusätzlich zu den Stegen 5 über das Endstück 10 miteinander verbunden. Diese Endstücke weisen eine Endplatte 11 auf, die an dem Gestell bzw. den Längsholmen eines Lattenrost-Rahmen (beide nicht dargestellt) flächig anliegt und mit Stiften, Schrauben oder auch mit Dübeln festgelegt werden kann. Vorteilhaft werden die Endstücke 10 mit Stiften oder Schrauben angeschossen. Weiterhin können zur Abstützung an die Endplatte 11 Laschen 12 angeformt sein, wobei Endplatten 11 und Laschen 12 so konfiguriert sind, dass sich die Laschen 12 auf oder in dem Gestell des Sitz- oder Liegemöbels bzw. den Längsholmen des Rahmens des Lattenrostes eines Bettes abstützen. Dazu stehen diese Laschen 12 etwa rechtwinklig von den Endplatten 11 ab.On the slat head 2, the two outer ends of the U-profiles 3 and 4 are connected to each other in addition to the webs 5 via the tail 10. These end pieces have an end plate 11 which rests flat on the frame or the longitudinal members of a slatted frame (both not shown) and can be fixed with pins, screws or with dowels. Advantageously, the end pieces 10 are shot with pins or screws. Further, tabs 12 may be formed to support the end panel 11, with end panels 11 and tabs 12 configured to support the tabs 12 on or in the frame of the recliner or the longitudinal beams of the frame of the bedstead of a bed. For this purpose, these tabs 12 are approximately at right angles from the end plates 11.

Bei der Montage stellen diese Laschen 12 sicher, dass die Lattenkörper 1 gegenüber der Oberkante des Gestells bzw. der Längsholme in einheitlichem Abstand liegen.During assembly, these tabs 12 ensure that the slats 1 are at a uniform distance from the upper edge of the frame or the longitudinal members.
